Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a mobility load balancing method and an access network device.
  • Network sharing among multiple operators can save the cost of network construction and shorten the cycle of network construction, mainly including the sharing of telecommunications network infrastructures (for example, station addresses, facilities in an equipment room, towers, power equipment, and other sites), and sharing of network devices (relevant facilities of telecommunications network equipment such as a base station, transmission and core networks).
  • Radio access network sharing is an important network sharing technology.
  • the user equipments corresponding to multiple operators can share the same base station or cell.
  • Mobility load balancing (Mobility Load Balancing, MLB) technology is an important technology for solving the problem of unbalanced mobility load.

That is, the load of each cell is evaluated according to the situation of the resources occupied by the services of all the user equipments in each cell, and after load information is exchanged with adjacent cells and a load balancing target decision is made, load balancing is performed on the cell with a higher load. Specifically, the cell with a higher load selects, from all the user equipments in the cell, a part of user equipments for handover.
